The control unit of power couple relationships response from the accelerator entry of air and petrol into the cylinders a car regulates some parameters related to engine performance, more precisely: With the ECU remapping operation we will be able to change various parameters and therefore we will free up the true potential of your engine. The process to be done is absolutely safe and all the thermodynamic parameters of the engine will be made more efficient by optimizing their performance. In concrete terms, this operation works through a computer that must be connected to the control unit and in this way the parameters of the parent company can be assigned and modified according to your needs. If we go into specifics, there are two types of mapping: the traditional one and the serial one. The traditional remapping takes place by opening the engine control unit and making physical changes, the mechanical workshop in this way will have to intervene by tampering with the main control unit and it is important that it is still under warranty to carry out this operation, the serial mapping instead allows you to reprogram the ECU data without compromising the machine warranty.
